Question
9) Finding a small value of the p-value (e.g. less than 5%) A) indicates evidence in favor of the null hypothesis. B) implies that the t-statistic is less than 1.96. C) indicates evidence against the null hypothesis. D) will only happen roughly one in twenty samples. You have collected data for 200 countries and estimated the following relationship between the change in the unemployment rate from the previous year (Aur) and the growth rate of the respective state real GDP (gy). The results are as follows Aur 2.81 0.23x gy, R2 0.36, SER 0.78 (0.12) (0.04) The 95% confidence interval for the slope is approximately the interval A) [2.57, 3.05] B) I-0.31,0.15] C[-0.31,-0.15] 0,31 0 ) Using 143 observations, assume that you had estimated a simple regresion function and that your 11) Using 143 observ estimate for the slope was 0.04, with a standard error of 0.01. You want to test whether or not the estim is statistically significant. Which of the following possible decisions is correct? A) you decide that the coefficient is small and hence most likely is zero in the population B) the slope is statistically significant since it is four standard errors away from zero C) the response of Y given a change in X must be economically important since it is statistically significant D) since the slope is very small, so must be the regression R2Explanation / Answer
9) C) indicates evidence against the null hypothesis.
10) C) [-0.31, -0.15]
11) C) the response of Y given a change in X must be economically importance since it is statistically significant.
